Implement custom '.pick()' for objects

const pick = (obj = {}, keys = []) => {
  const result = {};

  for (const key in obj) {
    if (keys.includes(key)) {
      result[key] = obj[key];
    }
  }
  return result;
};

const obj = {
  name: "Mehul",
  age: 27,
  email: "codedrops.tech@gmail.com",
  website: "codedrops.tech",
};

const keysToInclude = ["name", "age"];

console.log(pick(obj, keysToInclude)); // { name: 'Mehul', age: 27 }
